  • Publication number: 20240135832
    Abstract: A system may receive inputs selecting an interest level from among a plurality of interest levels for each of a set of topics. the system may determine displayable information describing a subset of the set of topics based on the inputs, which displayable information may include media segments. The system may generate a sequence for the displayable information for the subset of topics using the inputs and defined ordering criteria, and it may present, for display in a graphical user interface on a client device, a digital demonstration including the sequence of the displayable information for the subset of topics.

  • Publication number: 20230261693
    Abstract: Provided herein are circuits and methods for processing samples of a received in-phase and quadrature (I/Q) domain signal that includes a desired signal and an interference signal that spectrally overlaps the desired signal. In the I/Q domain, a first contribution to the interference signal is removed from the samples using a first algorithm to generate first processed signal samples. Amplitudes and phases of the first processed signal samples are obtained. In an amplitude domain, a second contribution to the interference signal is removed from the amplitudes of the first processed signal samples using a second algorithm to generate second processed signal samples. A signal quality metric of the second processed signal samples is obtained. Based on the signal quality metric of the second processed signal samples, one or more parameters of the first or second algorithm are adjusted to improve the signal quality metric of the second processed signal samples.

  • Patent number: 11588516
    Abstract: Under one aspect, a method is provided for processing a received signal, the received signal including a desired signal and an interference signal that spectrally overlaps the desired signal. The method can include obtaining an amplitude of the received signal. The method also can include obtaining an average amplitude of the received signal based on at least one prior amplitude of the received signal. The method also can include subtracting the amplitude from the average amplitude to obtain an amplitude residual. The method also can include, based upon an absolute value of the amplitude residual being less than or equal to a first threshold, inputting the received signal into an interference suppression algorithm so as to generate a first output including the desired signal with reduced contribution from the interference signal.

  • Patent number: 10340962
    Abstract: Under one aspect, a method for reducing interference in a received signal can include splitting a received signal into a first portion and a second portion, the received signal comprising a desired signal and an interference signal that spectrally overlaps the desired signal. The method also can include estimating an amplitude A(t) of the first portion as a function of time. The method also can include suppressing at least a portion of the interference signal in the estimated amplitude A(t) to generate an interference suppressed amplitude A?(t). The method also can include delaying the second portion by an amount of time corresponding to the estimation and suppression. The method also can include multiplying the interference suppressed amplitude A?(t) by the delayed second portion to obtain an output having reduced contribution from the interference signal.
